BUILDING BLOCK.

Application led February 25, 1925. Serial No. 11,456.

This invention relates to building blocks, and has for one of its objects to improve the general construction and appearance and increase the utility of articles of this character and to attain these ends I provide a building block having a facing of brick and a body made of plastic material.

With the above and other objects in View, the invention consists of the construction, combination and arrangement of parts hereinafter fully described and claimed, and illustrated in the accompanying drawing, wherein:

Figure l is a view in front elevation of'one form of building block constructed in aceordance with my invention,

Figure 2 is a similar view of another form of the building block,

Figure 3 is a sectional view takenon the horizontal plane indicated by the line 3-8 of Figure 2, and

Figure 4 is a sectional view taken on the vertical plane indicated by the line 4 4 of Figure 3.

Figure 5 is a fragmentary perspective of the block minus the facing units.

Corresponding and like parts are referred to in the following description, and designated in the several views of the drawing, by similar reference characters.'

In the drawing l designates the body and the facing of the building block. The body l may be made of'cement, concrete, mortar or the like, and is when occasion requires reinforced by rods 3. The body 1 may be of solid or hollow formation, and when of the latter formation it is provided with a central air space 4 and terminal air spaces 5.

lhe facing 2 consists of bricks'6 of any kind and configuration, embedded in the body l. The bricks 6 are preferably arranged in relatively spaced relation and extend a slight distance beyond' the outer side of the body'l, and are secured in place bv dove-tail ribs 1 and fitting bricks.

While but two forms of the block are shown in the drawing, it is to be understood 7 forming a part of the body in dove-tail recesses 8 in the tions of all walls and for ornamental decol ration of all types of buildings. The block shown in Figure 1 is of T-form and the one shown in Figure 2 is of rectangular formation. The block may be readily given any desired shape, and may be manufactured by hand in a form shaped along the lines' of the building in which it is to be used or it may be manufactured in any concrete block machine. Vhen a plurality of the blocks are assembled they ive an unbroken and ornamental surface. if for whatever purpose it is adapted, and it is particularly adapted for walls, faces, corners, cornices, sills, lintels or for any surface or any ornamental work in any and all types of buildings.

The drawing and particularly Figure 5 illustrates that the body of plastic material is provided in effect with a series of relatively spaced shallow recesses, the bottom walls of which have integrally formed dovetailed ribs 7 for interlocking engagement with the inner faces of the facing units 6. More specifically, the outer surfaces of the dovetailed ribs 7 are inwardly of the face of the body of plastic material so that the locking connection between the ribs 7 and the facing units is entirely within the recesses.

It will be understood that in practice the body 1 may be of any depth, width or thickness, and it is to be further understood that the depth of the brick facing may vary in practice to suit different conditions.

What I claim as my invention is In a building'block, the combination of a body of plastic material provided in a face thereof with relatively s aced recesses and having integrally forme dovetail ribs located entirely within and projecting from the bottom walls of the recesses, said ribs being of less thickness than the depth of said recesses, and` facing units located within said recesses and provided with dovetail grooves for the reception of said ribs.

In testimony whereof I ax my signature.

JULIUS E. VROMAN.
